IMPROVEMENT IN BEGUIA'IING ANI) DISPNSING-MBGHANISM.

Be it known that I, Soci-turns Scuonrrnnn, of Providence, in the countyof Providence, ond State of Rhode Island, have inventedY an ImprovementinRegulstirig or'Dispensing-Meohcnisms; and do herebydeclare that thefollowing is a full and exnct description, reference beinghad to theaccompanying drawings, making a part of' this specification. i

P The nntu'rc'of my invention consistsin o. ncw-nndpechliar applicationofnvibratin'g-bar or lever, for the purpose of starting, stopping,reversing, orchanging the action of machinery, without requiring orlinking l poiver from the indication or movement-Which showssuch uchange to be'desirdble.

My inventionV includes a 'vibrating-movement,commencing near or inconnection with the .device whose movement' wil-l cause the power' ofthe-machine to bedispensed a's-dcsired,-whicli device may be eitheraclutch, belt, catch, or dog, or other equivalennnvhich has no positiveor permanent connection with the governor, or other indicator of therequircdchange, thu'sleoving such 4-governorfor other indicator free toassume and pre-` serve a perfectly correct position under 'allcircumstances. New, by means of suitnblyfarranged pins,.notches,elevations, or depressions, (attached to or in proper-connection withagovernor, or other indicator, sofas tobe moved by the lsomo as theindication chsnges,) thepreviously-mentioned vihrting-movement canlle-obstructed, ns desired, :ind the power of such vibrating-movementwill vtlien be thrown upon the device arranged to change the action ofamachine. y l

This principle may bc applied to thc'purpose of regulating the speed ofmachinery, from the indication, by any kind of governor. Also, forregulating heat, from the .indication by o balcncedthermometer, or fronyany' other instrument in which thc required change is produced by heat,sind for ,a great number of similar purposes, being also Vapplicable asa stopmotion,'=in various machines where extreme scnsi-tiveness andVdelicacy are required.

r 'My invention alsoconsists in a. peculiar arrangement ofratchet-teeth, whereby such ratchet may lne-mode i' to assume andmaintain dierent positions, asr desired. One cxtreme may be appliedtocause in machinery a motion in ornefdirection, the other extreme toceusevmotion in .the opposite direction, :india-medium position-to causesuch motion to cease; or the different positions may be applied toproduce various degrees of the same motion in any'machine.

My inventionalso consists in a peculi'amirrangement for embodying theaction of a. regulator in the 'posii tion of certain elevations ordepressionsupon any suitable surface, Whether plane or curved, -thusmaking the f' regulator, without any alterationencept in changing theplates Vfurnished with such elevations or depressions, i capable of anyaction desired, i i i Bythe use ofthis improvement, a regulator can bemade toiict upon a gate to a waterewheel with gres-t rapidity, for thereason that the gate can be held stationery, or` moved iu eitherdirectio'nhnt'any time desired, Without regard tothe position of thegovernor.' A

To enable those skilled in the art to make end use my invention', I willproceed to describe its construction L ond operation'. i

Figures-1, 2,r and 8, of drawing A, represent `diiierent.views of anapplication of my improvements toa water-wheel regulator, made to act bythrowing into gear a more powerful machine, placed betweennitnnd thegate, figs. land 2 being side views, and g. 3 a top view of the same. mA represents n sliding collar, vwhich may be connected to the commonball, or any other kind of governor.

Upon agroov'e` inthe collar 'A' is placed the strap B, to which :ireattached the rack and notched hai-.(1. The i teeth of therack are cutfora space equolto the risc and fall of the governor, nndstrike into thegear E, turn# ing loosely `upontuhe shaft I, which isfsustnined'by theframework of the machine.

The hub of 'the arm'F is pressed agninst'the gear E by the nut H andspring G, ,thus forming, between the gear E und arm F, an ladjustablefriction-joint. The lower end of theIarm F is bent atright angles, andagotch I cut .to receive theflovver end of,'the barC, the width of thisnotch to be obout the width of the 'bar C.. Upon` each side of the bar.C are cut the notchesc c, which will allow thc arx-n F acertain amountbfinotin.v Upon the armF are .placed the pins dd', between which vibratethe'notchcd arm of the knee K. v i vThe segment L, to which the dogs orcatches M .M a'rc attached, receives a reciprocating motion from theeccentric, V. Uponthe segnient L is securedthe spring N, passing overthe notched segment l), and pressing Hwithconsiderablc force upon thevibrating-lever O, so that the friction may bc suicicnt to cause thelever tp partake ofthe reciprocatingmotion of the segmentL. `The le'vcrD is connected to the vibrating-knee K by the bar R.- l l l To thc,segment Pis connected thearin Q, Afrom the cndoi` which a connection-inay be made to another and separatelyfdriven-machiiie, tooperzntethegate. Theouter notches pp aro higher than the inner oncs,pp, and thatportion jo'` thcflcver OA which formstheratchct-guard is eitherinclined, or varranged in steps, so that the catches maybe raised orlowered, to conform to the notches ofthe segment P. In some cases l usea springcatch, instead of thc g1'avitating-catch shown inthe drawin lFig. 1 represents this machine at a point where the machine towvhich itis to beconnecterl has been thrown cnt of gear, andinas ceased to actonthe gate. New, if the collar A is depressed, -the action of the rackupon the gear Eondfrictionfjoint will belsuch as to cause the lower endof the arin F to'be moved to the `depth .of the notch c', and, if' themotion of 'the 'collar A should, continue, the gear E would turn uponthe shaftl, without imparting further motion to thcarm F; but as soon asthe motion'oi" the collar A takes a contrary direcltion, the lower endof'tvthe arm F will be moved back again through aspace equal tothcdeptlrof the notch c'. New, as, the vibrations of the catchesM M aretransmitted to the leverO by tbct'riction offtbo spring il, andthcnc'e,`by the bar R, to thcfline'e the previous movement' of the arm Fwill cause the pin J to obstruct the movement of the knee-K, oli.account of the step-like form of the notches at its, end, which vibratebetween. the Pins Jil/ I .I Now, themotion of-t-heikncc K being stopped,ythe motion of the lever O will also be'stoppcd, thesprirrg l N `andcatches passing overits surface to a new position, so that. the catch Mwillbe left free to act upon the notch p', thus depressing the' arrn Qto the position ,shown -in the lower `dotted lines, thus causing another,machine to be thrown into gear, by connecting with a. clutch, orsliding a'belt, or by changing the position of catches or dogs, or, byonyother convenient" means, causing the', machine todo thc work requiredte move 'the gate, A' I A Now, when the work 4performedhas'beensuiicicnt to so aiectthc speed as to cause the colla-r A to takea reverse direction, the arm F'will instantly resumets'formcrposition,'thc notched en rl ofthe knee K willstrike the pin J, 'thevmotion ofthe lever O will be obstructed, and the catches brought to. aposition in which they dan only operate upon the notches pp, whent'h'e'segment l? and arm Q will be brought back to their former position, vandthe intervening macbinenbecomc thrown out'of gear, and cease itsaction upon the gate, as before.

I The'same operation will take place it" the collar A is raised, butareverse action will be produced, 'raising the arm Q to the position ofthe ilppcrdottedflines, causing the intervening mochincto act upon thegate'in Aa contrary direction. y. v f i, Y

Figure 7 represents-a diiierent `method of arranging the vibrating-leverO'to raise or lower the catches, it being attached to theseguient L, ands uiiicient friction secured to hold it in place by means of the screwW, upon which it turns, orby any other suitable device.

The lever 0 is to be set by means of the inclined step-lilte notchesoperating between the pins JJ', the positionlof thesefpinsidetermini-ngwhich way the 'power of the regulating-mechanism shall act. `ThisarrangeL ment is peculiarly applicable tothose regulatorswhcre a racktakcs'thc place of the ratchet-gear X,and where a. direct reciprocatingmotion is iinpartedto the catches. I "The arm Y, upon which the pins J7are placed, may bc operated by a governor, for controlling and regujloting the speed of machinery, or it may be operated bythe pressurewithin a closed chamber, o r'boiler, or by the 'expansion andcontraction caused by'heat, for the purpose of controlling such pressureor degree of heat, or for any similar purpose..v

I `'libe' arrangement of a vibrating-lever or bar, held at any suitablepoint by friction, and placed in contact 'or connection with the devicetobevmo'ved, constitutesa new invention, whiclris applicable for variousregulating or dispensing purposes, and iscspeciallydesirable wherefthemovement from which the maehinemust bcmade to operate is very weak. Theslight directive'poweir'of tlie'magnetineedlc toward the north, ortoward another magnet, is, by this means, capable of becoming theinstrument-for changing the movement ofthe most powerfulvm-echal1'isnn,'the magnetic needle, with 'the necessary modifications,4taking the place of the arm F in' tig. 1, 'l

it is evident that the relative position 'of tho notches 'c' c and armvF, in iig. l, may be reversed, the rack and no'tclres remainingstationary, while the gear E and arm F are attached to the governor',the' operation andl l result being made the same as prcviouslydescribed.

' In g.`1, the notches c c are socutthat the regulating-mechanism shallact only whcnthc speed is departing from its medium rate, dnd ceasingits action when the extreme of variation has been reached.

Figure 4 represents the bar with notches s o cut that theregulating-mechanismmay commence its action as the variationin speedcommences, continuing its action until the greatest limit is attained,and reversing its action as the speed returns toits medium rate,thuscorrecting any surplus in its previous action on the gate.

Figures'5 and 6 represent an arrangcmentwhere the step-like notchesiareattached to the arm` F, and oper ate' upon the bar a', which ,is4attached toiand'moves back and forthwith the vibratinglever 0. 'If theratchet;- catches fare arranged to' operate upon a. rack, a.singlevibratiug-bar' andgudrd, operated and heldin position by friction,will be suiioient to produce the result desired.:

gAnother'illustration of the principle of controlling the acjtion ein;governor by means of suitable elevations ordepresion, similar to thenotches c c,.is shown in i'g. 1 of drawing though the notched leveror`bar there used to move a common ratchetgunrdis not inclnded'in myclaim, being`incapable of approaching inthe slightest de'grecthe extremelimit of sensitiveness :ind accuracy-tobo ottained'by the fuse ofmyimproved arrangement of' vibrating-'hars or levers, as shownin drawingsA and C. I' i i l A, infig. lof drawingB, .represents the Aslidingcollnrof agovernor, to `which `the strap B is attached.` R is connecting-bur,working loosely at the tivo joints a and Kis aber, furnished at one endwith inclined or step-lii:enotches, as shown, the otherend being jointedloosely to the lower p'art ofV the'vibrmjngkam` L whichearresthccatclies so that the notches ot' the bar K-wiil .partake Aofthereciprocating movcment'imparted tothevcatches, nndat the4 same time heeontrolled'in their'action upon the pins ofitho friction-collar N,'between which they vibratie, by the riscand fall of 'the governor. "lhefri'ction-collar'N slides upon the bar F, held loosclyat one end by theiixe'fl support c c, `the 'other' being jointe-Ito the lower part of theguard 0.

By screwing op the not g, a suilicient amount of'friction may besecured: to hold theguard securelyin place i@ when properly set by thenotion of the catches. The -bar C is also'sccuredtothmstrap B,J thelower end being held loosely by the {ixed supper-IVF F. This bar isfurnished with suitable elevations 'andv depressions, upon which thepins d dnct in: n. manner similar to the previous description in drawingA. i V i I V The various parts are represented in the drawing in vn.position where there is no action from the catches Vupon therntchet-wheel P. New, if the governor' .should rise,the'vibrating-notches of thev bar or lever K .will strikeagainst thepin-J,f therchy moving -the 'guard 0 until'thc pin allsftriitesv:rgalnstthe'sidoofithe bor C, when' a tooth oi" the ratchet-wheel? willVbefnncoveretl, and the'eatchcs will not. A continuation of the movementof the governorin th'e s zime direction, however, will not,nndcrthcarrangement shown, produce any 'further movevment in the guard, vthefrictiomcollar N'beingfmerely slipped-(along the bar. F, toward thesupport c'e, the bar Q' and pin d preventing any further movement ofv4the bar F in that `direction, but when-ever the direction of themotion'ot'fthe 'governrrohangem a reverseV a'ct'ionwill take place. i iV ,i

vAnother.errangement, operating by-means ofA my improved system ofvibrating-'bars-or levers, is shown in iig-15A of drawing C, where thenotchesovhich'rise and fall with the governordo not have-alreciprocating motion,` as shown in-drawing B. l i

represents the sliding collar of the governor,` with 'the' bar Catt-ached. "This bar is to be so held 4that its only motion shall be'with the rise'and fall of the governor. A movement greater'than thatofthe governor may beimparted to the bar C, by connecting `the same tothe collai` A by menus of a multiplying-'lever or by a. system ofgearing. Upon one side of the bar C is attach-ed thenotchedb'ar R. Thebar G is jointed to the arm' L, which carries. the catches and vibrateswith th'e sanno.V Upon this ber is placed the friction-coller N, or itsequivalent, with its'piiis 3121"., The outer end oi'fthe bar Gris heldby some ned'snpport.. To the friction-collai-N'is also'vat-t'ached thefriction-collar T,whic'.h operatsfupon the bar Fp which is jointed tothe vibratingdever 0, which raises .the catches. Upon thebar -F areplaced the pins d d, which operate against the bar G, andthns place thelever O in the required posi-tion with regard to the catches.v New., asthe bar C rises-with the governor,the vibrating frictio'r1-oollar y Nwill be movednlong the bar Gr toward the catches, and thisinovementfwill cause the pin dto vibrate Aagainst .the side of thebarbC,`thereby-keeping the vibrating-lever O in a. positionivhere oneof, the catches cannot. Now, when the movement-of the governor ichanges, 'the piu d willvibrate against the otherl side ot' the bar C,and the 'actionL of the catch will cease;4 The notched bar B. and 'ba-r@may be controlled by two separate governors, if desiredl The drawingsA, B, and C, illustrate some of thc various modes by which the actionotii. governor may be r transmitted, and its surplus absorbechby' africtional or any equivalent'de'vicmand be again referred to the t-directnction of 'a governor, in order to control either theextentorwtime of its action -on any dispensing-device; i and thispeculiar mode of action, irrespective of the arrangement and form of thedevices, Iclnini as my improvementin any regulator.

It is not necessary that the extreme' positions ofthe lever Oshould"befcontro1led bythe bar C, since it may he. easily limited byaxedrpoint not in connection with a governor, but it is essential thatthe point where the catches shall cease to act shall be sojcontrolledand'determined. i VIn the preceding examples the vibratinglever orbarbas been applied forthe purpose of raising o r lowering catches ordogs, which engage withratchet-teeth, and have themselvesareciprocati'ng motion; but the same principle is also applicable wherethe device' to ber moved in or out ofgear must, froniits nature, befhedsta.-` tionary during the intervals oi`- its required movement. Thearrangement for this purpose isshown in figs-1, 2, and 3.0i` drawing C.I l f The lever K iniig. 1 is jointed loosely upon one sideoi` o.ratchet-guard, O, and is to` receive ai reciprpcat A ingmotion, as shownbythe dotted lines, which may be imparted by the bei' R, jointed `at thepointk, or by any other suitable means. Thegnard' O being held in pinceby the 4friction of the. spring'uN, or by any-equiva lent, can 'only bemoved by obstructing the movement'of theouter end of the bnr K, whichmay be made to strike against notches or pins, in ordertoproduce themovement desired; V .V i Fig. 2.shows the application of this lever tothe clutch S, which is to be so arranged, bynieans of suitable frictionor otherwise, as to'keep its place when once set by the action'oi' thelever K; Fig. 3 representsthe application of the lever tomove ebelt.`'The outer end ofthe vibrating-lever K being4 obstructed by any suitablemeans, the power is immediately directed to move the guide whichcontrols theposia tion of the belt. The vibrating-leverK may bemod-iiied and arranged in various ways, but the .examples shownsufficiently' exemplify the p'rinciplcinvolvd. v V i i n i A 'lhe modeofaction by the vibrating-bar or lever K, as shown in tigsl, 2, and 8ofdrawing C, is-the reverse i of that of the bar K, shown in iig. 1ofdrawing B, since with thcifi-rstwe startjrom n. ratchetfguard, clutch,or belt-guide, and from thencevihrntc 'towardjthc partthemovem-eu't of`whichis tocauso a changel in the'position of such guard,cl utch,jorhcltlguide, and` in the' other case wecommencel with a positiveconnection to the govemol-,and vibrate toward the part whose movementwill-produce the required ohnngeint-he power or' action of the machine.

I cla-im as my invention, commencing at that port of al machine whichdispenses the povrer,`r'changes its action, and from thence vibratingtowzird that part whose movement is, to govern A.such dispens'ation,examples of whichare shown in drawings-Annd C, vand Ido not claim n.vibrating-lever or arm, 'when in direct and positive eonneotion withany governor, or with any other similar devicewhose change ot" positionor indication should'prodnce a change in the action of any machine. Y l

4 The advantage of the `previously-described arrangement is evident,since, with myimproveinent, the action of a. powerful ina-chine may, bechanged without in anydegree interfering `with thecorreot actionof'thzit which is t-o canse the change, however lv-oak tlie'reqniredindication may be, which is n metter of greatimportnncc in many cases. lv

Hoving thus described my invention, and what I deem` to be aieniii'cient cxemplicution o? the various methods of carrying it intoecet, what I claim as my invention, and desire to Secure by LettersPatent, s

1. Causing the motion derived from :my kind of governor, as transmittedin one direction, to be topp'cd nn-d controlled by anobstructing pointor'notch, or system of elevations or depressions, operating under. the

action of a. governor, transmitted in another direction, enbst-antinllyr:1s described.

2. Arranging the ratchet-teeth in steps, or one above the other, inconnection Witlra. guard operating to producen corresponding change inthe oievationoi' the notches,substantially as and for the purposespecified, in any regulating or dispensing-mechanism.

` 3. The combination of severol elements, consisting, {irstoi` a,dispensing-device,second, of ai vibrating-bnr or lever, and third, ofanopposing -point, placed in connection or combination with any governoror other indicator ofn desired change in the action .of a, mnohino, tooperate substantially 'as described.
